🔍 Key Concepts

• Relationship between number of cylinders and number of power strokes in a two-stroke diesel engine • Difference between two-stroke and four-stroke power events per crankshaft revolution • How often each cylinder in a two-stroke engine has a power stroke per crankshaft revolution

💭 Think About

• First, think about what happens in one full crankshaft revolution in a two-stroke engine: how many strokes occur, and on which stroke does the power event happen? • If you know how often one cylinder fires in a two-stroke per revolution, how can you scale that up for eight cylinders? • Compare this to a four-stroke engine: how many power strokes per cylinder per two revolutions—and how would that be different in a two-stroke?

✅ Before You Answer

• Be clear that in a two-stroke engine, each cylinder has a power stroke every revolution, not every two revolutions. • Confirm how many power strokes per revolution per cylinder occur, then multiply by the number of cylinders (8). • Make sure you are counting power strokes, not cylinders, and tying it specifically to one crankshaft revolution.
